To all whom it may concernlle it known that .l. linear-inn (it nwnor, asuh ieet of the King of Prussia. residing at No. ll d'orinserstrasse. inthe city of lien tin. German Empire. have invented certain new anduset'ul improvements in Machines tor lroduoing Fabric. Paper, ortlardbmird Having: an lnelosui'e of Cross ing: 'lhreads; and I do herebydeclare the following; to he a toll. dear, and exact deaeription ot' thesame.

his" in ention relates to a machine for prodneihQ' 'lahrie'. paper. orr-ard board having an ii'ielosure ot' eros. ng threads, preferably ofCrossing metal wires. A process for prodin-in; paper with such aninelosure is known. zit-wording to whit-h a series of longitudinal wiresor the like is introdut'ed betwe n two widths of paper or tabrit',whereupon a HQI'lOH of transverse wires is inserted. so that. onstirking the widths of paper together. which is done in the well knownroll sinking machine. the wire in closure is fastened. in theprot-esseis and ioat'hinee of this kind heretofore known the threadsinserted aeross the loi'igitudinal threads were inserted in. a more orless loose rendition. that is without suttirient tension. 'lhesetransverse threads were not able to prevent the paper from being torn.because they were only able to otter resistanee after the paper had beenbroken. lhis drawbaek orert'oine by my invention. as I insert thetransverse threads under tension and keep them stretehed. until they aretightly grasped by the pressure roll of the sticking mat-hiue and eannotget out of position. in my invention the transverse threads are raun'htat their tree ends and are pulled at a oertain tension from a spool. andthen. while still retaining this tension, are introdured. parallel toeaeh other. into the apparatus designed to t-ombine the separate widths.my maehiue being provided with suitable derives. whieh enable the wireto he kept under tensit n. ;,nntil it is taken hold of by the pressurerolls: and cut.

tin the accompanying drawing illustratin r sueh a niarhine by 'ay ofexample, l igntre t is a side elevation and a part seetion on the lineA-B of Fig. 2. Fig. 2, a plan of the front part of the machine. and Fig.a front elevation. while Figs. 'l:-l 1 show details.

The two widths of fabric, paper or the like. are combined with the wireinclosure between the two rolls 1 of the sticking inaohine. To theserolls thepaper width is led from above. while the paper width 3 inintrodueed from below. The lower paper width 3 is previously passed overa. roll 4. whit-h rotates in a vessel 5 containing an adhesive. so thatthis adhesive is applied to one side of the paper width Bet ween thewidths of paper 2 and 3 a series of longitudinal wires it areintrmlueed. which are wound otl spools 7. At the same time the wires 8are introduced between the widths at an angle to the longitudinal wire6. By the pressure of the rolls '1 the paper widths are continued andthe wire inelosnre is thus fixed. 'lhe finished paper with inelosnrethen led in suitable manner over a drying drum 9. hiarhines oi this kindare already' known so that a more detailed description will not heneeessanv.

My invention relates to the manner of introducing: the transverse wires.The apparatus. as above mentioned. must fulfil the conditions that saidtransverse wires are in serted parallel to eaeh other and at a rightangle to the longitudinal wires. and that.

before all. the transverse wires are kept under tension. until they aretaken hold of by the pressure rolls of the maehine.

Arvin-ding to my invention the series of transverse wires H are gi'iidedand moved to ward the pressure rolls 1 by two rotary disks it). it.which are provided in the same. horizontal plane. Said disks to. 11rotate'abtait their vertical axes at a unilorm speed in oppositedirertions. ()n the disk is provided a number of wire spools 12 at auniform eireuinterential distance from each other, from each of whichspools a wire passes to a nozzle 13 provided at the edge of the disk.(lot-responding to earh nozzle 13 there is a gripping device 14 on therotary disk 11. Said grip 'iingg devices 14 are so arranged at the edgeof the disk 11 that at the point at r" tat which the circumferences ofthe two disks 10, 11 are nearest together, a nozzle 13 is always exactlyopposite a gripper 1-1. At this point the gripper 1 the construction andoperation of which I will describe bclow, seizes the end of the wireprojecting out of the nozzle 13. According; as the distance of therespective nozzles and grippers, owing to the rotation of the disks 10,11, increases, the wires will be drawn d the spools 12 and introducedparallel to each other between the pressure rolls 1.

In order to explain the manner of guiding the wire from the spool 12- tothe nozzle 13 I refer to Figs. i-6. Fig. l is a radial sec-- tionthrough the outer part of the horizontal disk 10. Fig. is plan thereofand Fig. ll a section on the line. C-l3 of Fig". The wire drawn oil thespool 12 is first led around tightening pins 15 secured to the disk andthen through the slot 16 of a guide piece 1'? and under the roll 18,which rotates about the cylindrical part of a screw 20 inserted in theforked end 21 of a bell crank lever 22. From the roll 18 the wire passesover a cross piece :23 and through a guide 24 on the dish 10 and thentlllOllQll the nozzle 13. In order to prevent the wire from beinginjured by the front edge of the nozzle 13 a roll 25 is arranged infront thereof. As soon as the respective gripper ll has seized theprojecting free end, the wire 8 is subjected to a certain tension andthe bell crank lever which can rotate about the pivot. 26 in the guideblock is gradually raised until it reaches the position 22 shown indotted lines in Fig. l. The highest position of the lever 22 isdetern'iined by the stop 27, which then bears against the top edge ofthe lever. As soon as the. pull at the end of the wire 8' projecting outof the nozzle ceases, that. is, as explained below, when the wire iscut. the bell crank lever falls again by rcasoi'i of its own weight. Itthen pulls the wire 8" back to such an extent thatv only asmall pieceprojects through the nozzle 13, which is adapted to be caught by one ofthe grippers 14-, as soon as the disks 10. 11 have described completerevolution. In this wa) all waste ofwire is avoided and the gripper iscaused to takehold of the wire at its end. By the wire being pulled backthrough the nozzle, the free end, which as evident from Fig. 2, is bentsidewise over the roll 25 by the lateral pull, will be straightened.

in order to assure that the wires, when being drawn oil their spools l2receive a certain tension, a special brake is provided for each spool 12(Fig. 7). ()n the circiunferonce of each spool bears a brake block 28,which is carried by a spring 29. The inner ends of these springs are allfastened to a. ring 30. which is connected to the disk 10 in suitablemanner (l 1'). As soon as one of the wires 8, owing to the rotarymoremeat of the disks l0, ll has been brought close to the pressurerollers .l the bra he is put on, so that the rotation of: thecori'cspomliug spool 12 is retarded. and, us a camsequcwgex, the wirereceives a considerable tension. 'Illhc. brake is put on with theassistance of a stop ill, which is secured to a rail 32 carried by theframe of the inacbii'ic. This stop ill, the bottom of which is suitablycurved. projects down solar that the spring 29 passing there under isdepressed and the respective brake block 28 accordingly pressed arainsl; the spool. The stop 31 is so arranged that the spool 12 is stillretarded some short time after the wires between the pressure rolls havebeen cut oil. Bf, this means the spool is prevented from being rctatcdfurther by momentum, which would cause the wire to become loose on thespool or entangled, and would occasion disturbances in the opcratimi ofthe machine. This. and all unnecessary unwinding of the spools, areprci'cnlwl by the action of the brakes.

In order to reduce the friction of the spring 21) on passing under thestop ill. rolls may be provided under the stop 31. as shown, forexample. in Fig. 8.

As soon as a transverse wire 8 has been introduced between the pressurerolls, it. must of course be cut. oil. For this purpose the axes 34: ofthe rolls 1. are provided with circular cutters. the ope 'ation ofwhich. will be evident from F which shows the particular part of thepressure rolls in front elevation. Fig. 10 is a section on the linell-l? oil. Fig. 9.

Should it occur that. one of the wires is cut oil before it has beenproperly taltcu hold of by the pressure rolls 1 and fastcncd between thepaper widths 2 and Il. said wire mightv los tension. Tliis must howeverbe avoided. because otherwise the strength of the material producedwould be impaired. Now the rotating disks 10. 11 are so arranged inregard to the pre sure rolls 1 that the wire is not cut: oil, until itis held by the rolls. It is however preferable to provide an auxiliarydevice consisting of? two disks 36 of rubber or other similarmatei'ial,which are provided on one side of the circular cutters on the axes 34-ot the rolls 1. 'lhesc disks have a somewhat larger diameter than thecircular cutters 35, so that they come into contact. with each other inad 'ance of the vertical middle of the rolls 1 and are thus somewhatflattened, as shown in Fig. 10. lletwccn these llattcned portions of thedisk 36 the wire is held until it is fastened in position by the paperwidths being stuck together. The same clicct. would of course beobtained. if a disk 36 of elastic material were provided on the axis ofone of tl e circular cutters and press against the flange of the othercircular cutter. The elastic disk would also be flattened by pres sureagainst the llange and thus hold the wire. A corresponding devicepreferably provided on the opposite side ot the pres sure rolls, inorder to balance any differences in letting hold of the Wire. Instead ofconstructing the cutting device to cut the wires as soon as they arrivebetween the pressure rolls. said device may be so arranged as to out theu after they have left the rolls. For this purpose the cutters may, for(5X- an )le, be fitted on special axes behind the are rolls instead ofon the axes of these latter.

The cinistructum and operation of the grippers carried by the disk 11,which, at a. suitable mon'xent, catch the free ends of the wiresprojecting through the nozzles is shown in Figs. 11-14. '11 is a radialsection through the outer part or the dish 11 and shows the closedgripping device in side elevation. Fig. .12 is a section on the linelrl--ll of Fig. 1.1, Fig. 13, a plan, and let, a side elevationcorresponding to Fig. 11, showing; the gripper in the open position. Thewire is held between the ribbed jaw; 37, 38 of the gripper H. The upperjaw 37 is fastened to an angularly bent guide piece 39 and the lower jaw38 to a guide piece 40, which has also an anp'ularly bent shape. Theguide pieces 35}, l 1' n vertical guides 11, t2. which enable the pawsto he opened by a movement parallel to each other. This movement iseffected by a all 43, the back end of which rests in a fork ll providedon the disk ll, and is provided with a longitudinal slot -15, throughwhich passes a bolt 46 carried by the fork i The front forked end ll ofthe rail 4-3 is jointed by a pin 4-8 to a rod 4-9, the other end ofwhich attached to a disk 50 adapted to turnv about the pin A slot 51 ofthis disk tits on a pin attached to the guide piece 40 on the lower jaw38, while a. second slot tits on a pin provided on the guide piece 539oi. the upper jaw 37. If the rail is moved inward as far as possible (tothe right according to Fig. 11) the link 49 will occupy a verticalposition. and the two jaws 3T, 38 of the gripper will be closed. ithowever the rail 4-3 is moved outward (to the left according to Fig. 11)the link 4-9 and the di k connected thereto will be moved into aninclined position. As a consequence the lower jaw will be moved downwardby the pin 52 and the upper jaw upward by the pin 54, so that thegripper will be opened, as shown in lfig. 14 The movement of the railnecessary to open the jaws of the gripper is obtained by a curve 55secured to a cross rail of the frame over the disk 11. Against thiscurve 553 presses a roll 56 at thebach end of the rail 43. As aconsequence the rail. at?) is pressed outward (to the left according toFig. 11) and the gripper is opened. At the same time the springs 57 arebent, which at one end, are fastened to a book 58 attached to the rotarydisk ll, and at the other end, to a pin 59 fastened to the rail 43.Between the open jaws the end of the wire projecting through the nozzle13 can pass. Owing to the fun ther rotation oil the disk the roll. 56passes oil the curve 55, whereupon the rail all will he moved inward bythe springs 57 (to the right. according to Fig. 11), so that the jawswill be closed and the wire between them held fast. Said wire is thusheld, until it passes between, the pressure rolls 1. At this moment. theroll 56 atthe lvacl; end. of the rail 43 will bear against the secondcurve 60. The rail 43 will be moved outward again, the gripper opened,and the wire accordingly released. As soon as the roll -56 lea ves thecurve (30 the gripper closes again and remains closed until the roll 56,owing to the rotation of the disk again reaches the curve 55, whereuponthe described operation will be repeated.

It now it should happen that the end of the wire projecting through thenozzle 13 does not take a horizontal position, but is bent somewhat upor down, it might occur that it will not pass between the jaws 37. 38,butslip over one of the same. In order to prevent this, there isprovided in ad Vance of the point, where the gripper has to catch thewire, a guide 61, which is about concentric to the disk 10. This guideis shown in Figs. 1 -17 Fig. 15 is a side elevation, Fig. 16, a. planand Fig. 17, a section on the line l--li of Fig. 16. The guide consistssubstantially of two parts 62, 63, between which there is an opening6st. 'At their outer ends the parts (32, 63 are bent outwardly, as shownin Fig. 15. The opening 65, which is wide at the end and graduallydecreases in width in passing into the opening (ll. causes the end ofthe wire projecting through the nozzle to be led, during; the rotationof the disks 10. 11, exactly between the jaws 37, 38 of the gripper 14.The disks 10, 11 are rotated by the spurwheels (36, 67 keyed to the axesof these disks. In the spur-wheel 66 engages'a spurwheel (38, which isrotated through the agency of. the bevel gearing 69 by the driving shaft70, carrying the pulley 71. From the spur-wheel (i the motion istransferred to the spur-wheel 67 by the interu'zediate wheels 72 in sucha way, that the two disks 1.0, 11 are rotated at the same speed, but inopposite directions.

The speed at which the cross wires 8 are fed to the pressure rolls 1 canbe regulated.

not only by suitable construction of the gearing, but also by choosing alarger or smaller number of spools 12 on the disk 10 and a correspondingnumber of grippers 14 on the disk 11.

I do not desire to limit myself to the preill-5 else details ofconstruction and arrangement herein shown and. described, as it isobvious that various uujidiliculions may he made therein without de'iarting from the essential features of my lILVGlltlOIl as defined inthe appended claims.
